Abstract
The utility model relates to a part of the direct-current motor-a commutator, more specifically an integral commutator for direct-current motor, comprising a pressing ring, a commutator bar assembly and a sleeve barrel. The commutator bar assembly is an integral structure pressed and arranged by an integral commutator bar with an ascending slice. Compared with the exiting commutator for the large-sized direct-current motor, the utility model adopts the integral commutator bar, namely the commutator bar with the ascending slice formed by the integral punching, and overcomes the problem brought by the welding of the ascending slice and the commutator bar in the prior art. The commutator is provided with slots separately on the working surface of the commutator bar assembly; no-woof belts are bound in the slots. Through the structure, the deformation of the commutator is controlled within the preset range to ensure that the motor is in more reliable running. The integral commutator for large-sized direct-current motor of the utility model has more reasonable structure to cause the direct-current motor to run more reliably. The integral commutator is especially applicable for the large-sized steel rolling direct-current motor.
Description
Technical field
The utility model relates to the parts of direct current machine---commutator, is specially a kind of integral type DC motor commutator.
Background technology
Commutator is the critical component of direct current machine, and its quality concerns that can direct current machine normally move.The winding conducting wire sectional dimension of large-scale dc motor is bigger, and special winding conducting wire cross-sectional length is bigger, and the wire casing undersize of general commutator segment is connected with reliable realization commutator segment and winding line end.Therefore the commutator of large-scale dc motor mostly adopts the structure of welding rise piece, and promptly welding (as soldering) has rise piece in the commutator segment wire casing, can realize reliable connection between winding line end and the commutator segment by rise piece (having wire casing on it); But this kind structure easily causes rise piece fracture, and owing to when motor commutation generation arcing or ring fire, may make the melts soldering tin in the commutator riser wire casing, causes and get rid of tin and winding interturn short-circuit.Long-play causes the accumulation of carbon dust at rise piece simultaneously, forms potential faults.In addition, the commutator working face of large-scale dc motor is longer, and motor when rotation produces amount of deflection, causes the commutator distortion, and rotating speed is high more, be out of shape greatly more, when distortion during above a threshold value, will have a strong impact on the normal operation of motor.Often to increase the commutator radial dimension for this reason.
Summary of the invention
The utility model provides a kind of integral type commutator of large-scale dc motor at the above-mentioned defective and the deficiency of the commutator existence of large-scale dc motor.
The utility model is to adopt following technical scheme to realize: the integral type commutator of large-scale dc motor, comprise trim ring, commutator segment assembling, sleeve, and its commutator segment assembling is to press-fit the monolithic construction that forms by the integral type commutator segment that has rise piece on it.Compare with the commutator of existing large-scale dc motor, the utility model has adopted the integral type commutator segment, the commutator segment that promptly has rise piece is that integral body is stamped to form, and has overcome the problem that rise piece and commutator segment welding are brought in the prior art.
This commutator has groove in the compartment of terrain on the working face of commutator segment assembling, colligation has or not the latitude band in the groove.Deformation control by this structure commutator guarantees more reliability service of motor in prescribed limit.
The integral type commutator structure of large-scale dc motor described in the utility model is more reasonable, can make the operation of direct current machine more reliable.This integral type commutator is specially adapted to large-scale steel rolling DC motor.
